PDC Machines has been manufacturing industrial high pressure gas compressors since 1977. With decades of experience in diaphragm compressor technology, we have partnered with companies and government agencies worldwide to provide them with the optimum solution to satisfy their gas compression needs. We have developed an extensive line of basic diaphragm compressors and fully automated turnkey diaphragm process gas compressor systems with installations located around the globe. We design basic to fully instrumented oil free reciprocating diaphragm gas compression systems in accordance with customer specifications. Our compressors range in size from 3 hp(2 kW) to 250 hp(186 kW). Discharge pressures range from 50 psi to as high as 45,000 psi (3,100 bar). Diaphragm Gas Compressors Explained: Theory of Operation A diaphragm compressor is a positive displacement machine which consists of a hydraulic system and a gas compression system. Diaphragm compressors are somewhat traditional in the sense that the hydraulic system uses a linear reciprocating piston attached to a crank shaft that is driven by an electric motor. The hydraulic piston travels through a cylinder which moves a column of oil. This oil is used to lubricate the lower end running gear and to energize the gas process system. The gas processing system consists of the gas head assembly, three metal diaphragm plates and the compressor check valves. When the hydraulic oil is pumped to the underside of the diaphragm set they flex through a contoured cavity in the gas head as the compressor check valves allow for the process gas to flow in & out of the compressor.
